Make maven's surefire show stacktrace in console

Question

I'd like to see the stacktrace of unit tests in the console. Does surefire support this?

Answer 1

You can use the following command to see the stack trace on console instead of report files in the target/surefire-reports folder:

mvn -Dsurefire.useFile=false test

This only have logger output into console, but stacktraces still goes to surefire-reports – Kristalkristan

The answer using trimStackTrace is better! – Uterus

Answer 2

A related problem that I found is that surefire in recent versions apparently sets trimStackTrace to true by default (rendering most stack trace in failed tests useless), which is quite inconvenient.

Setting -DtrimStackTrace=false or defining

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <trimStackTrace>false</trimStackTrace>
    </configuration>
</plugin>

solved this.

Yep. Not only does Maven print pages of pointless diarrhea, but it hides what you actually need to see. – Extreme

I created an issue about this wrong default issues.apache.org/jira/browse/SUREFIRE-1457. Please comment it to help its reopening. – Berserk

@RédaHousniAlaoui Seems they moved it to another issue for JUnit 5: issues.apache.org/jira/browse/SUREFIRE-1432 Just voted there. – Diaconal

I set both 'trinStackTrace' and 'useFile' to false... and still I'm just getting no stack traces for my test failures :-( – Insane

@Insane do you means stack traces has lots of line, the output show ... 26 more? – Anacreon

Default is now trimStackTrace=false in 3.0.0-M6. However, we're still using 3.0.0-M5 ... :--) – Owlet

To extend the answer given before, you also can configure this behavior in your pom.xml:

    ...
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.5</version>
      <configuration>
        <useFile>false</useFile>
      </configuration>
    </plugin>
    ...
